POLYDROSUS. 213 
British Museum was received in 1863; it is labelled “ Phyllobius grypsatus, Schonh., 
var.,” but has nothing to do with that species. 
8. Polydrosus amplipennis, sp.n. (Tab. IX. figg. 9, 9a, 2.) 
9. Elongate-piriform, piceous, the elytra brown, the legs testaceous or obscure testaceous ; densely clothed 
with subopaque golden-green scales, the legs also with a few green scales amongst the fine hairs. 
Rostrum sinuate on each side behind the points of insertion of the antenna, finely longitudinally sulcate 
towards the v-shaped ridge bordering the nasal plate, the scrobes deep and descending to the lower 
surface. Eyes moderately large, prominent, distant from the front of the prothorax. Antenne com- 
paratively stout, long, the scape nearly reaching the prothorax, joint 2 of the funiculus shorter than 1, 
3-7 decreasing in length. Prothorax transverse, subconical, at the base broader than the head with 
the eyes. Elytra long, inflated, rapidly widening to the middle (and there more than twice as wide as 
the prothorax) and obliquely narrowed thence to the conjointly produced rather narrow apices ; finely 
punctate-striate, the interstices somewhat convex. Legs elongate. 
Length 54-6, breadth 23-22 millim. 
Hab. Mexico, “ Sierra de Durango” (Hoge, ex Solar?). 
Two specimens, one abraded. Larger than any of the other species of the genus 
here described, the elytra long, inflated, and acuminate, the prothorax small and sub- 
conical, the antennze comparatively stout, the scrobes descending, the body elongate- 
piriform in shape, perhaps narrower in the male U 
9. Polydrosus chlorogaster, sp.n. (Tub. IX. figg. 10, 10a, 2.) 
2. Elongate, piceous, the antenne (the black club excepted) and legs ferruginous; the sides of the head, 
prothorax, and elytra, and the under surface densely clothed with metallic green scales, the upper surface 
with coppery-brown scales to near the apex, the dark space on the elytra sharply detined laterally, 
angularly excised behind, enclosing a common v-shaped pale cupreous patch, at about the middle of the 
suture, and followed by a subapical similarly coloured fascia, the legs sparsely pilose. Rostrum 
constricted behind the points of insertion of the antenne, the nasal plate short, arcuate, the scrobes deep, 
sinuate, extending beneath the eyes, and partly visible from above. Antenne long, the scape reaching to 
the front of the prothorax ; joint 2 of the funiculus as long as 1, 3-7 slightly decreasing in length. Hyes 
large. Prothorax transverse, subcylindrical, feebly constricted anteriorly, finely, densely punctate. 
Elytra much wider than the prothorax, long, gradually widened to the middle. produced at the apex; 
finely punctate-striate, the interstices feebly convex. Legs elongate. 
Length 54, breadth 13 millim. 
Hab. Guatemata, Quiche Mts. 7000-9000 feet (Champion). 
One specimen. A peculiar form, approaching the Palearctic P. fuscoroseus, Desbr., 
with the scales on the upper and under surfaces very differently coloured, the coppery- 
brown space above extending from the tip of the rostrum to near the apex and 
‘angularly excised posteriorly. 
10. Polydrosus acuminatus, sp.n. (Tab. IX. figg. 11, Ll ¢.) 
Oblong, piceous, the antenne ferruginous or testaceous at the base; densely clothed, the legs included, with 
metallic green scales, the upper surface also set with very short, fine, suberect, pallid hairs, those on the 
elytra uniseriately arranged down each interstice. Head rather small; rostrum constricted behind the 
points of insertion of the antenne, with the nasal plate narrow, triangular, and the scrobes deep, angulate, 
descending beneath the eyes, and partly visible from above; antenne comparatively short, the scape
